Would you say that Wadokai is the exception or the norm Nick? Even if Aikido does train some grappling techniques (for it was not my intent to imply that ground was completely foreign to Aikido), it doesnŽt come near the specialization or depth of ground work which JJ develops. I would encourage you to attend, youŽd find it enlightening, as would most Aikidoka.
At your service,
